243ai loads

[hunter243sgk]

I am waiting on a 243ai barrel and don't have any load data.I don't know why I could not start with mid range 243 loads and work up.I have always heard it takes a stout load to properly form the brass.What is the best way to get started.As this is my first ai i could use any ideas i can get.Thanks

To start with any weight for fireforming.Then I will be looking for loads for the 105a-maxs to the 75g pills.I have sent them a dummy round with the 105g a-max on it.I have a lot of 58g v-maxs so that is what I would like to fireform with.

Fireforming you'll shoot a standard case in a chamber that's larger than standard. You don't back off on the load. Whatever the reloading book has for a max load, start there and work your way up until best accuracy. My fireform load was a 70gr TNT and 48+ gr. of W760. Very accurate and much faster than a std. .243. Perfectly formed case every time.

Thanks ackman.I thought that's what I had read before.How much after max do you go on the average.I know all guns will be different but just curios how far past max are you getting?

Got it.I should have checked my reloading manual before I asked.As it shows max being 46gs.
